Using UniversalImageLoader with WebView - android

I am using Android Universal Image Loader in my application. It works great for ImageViews, but I also have WebView in my application. Therefore, images are downloaded twice. Once by Universal Image Loader for ImageViews and once by WebView. Is it possible to use the already downloaded image in WebView?

I don't know if it is answer to your question but look at here maybe it helps you.

How to load images from internet in android app quickly?

I'm a beginner in android and i want to load some images from internet in my app. I heard about libraries such as Glide and Picasso. Can anyone please tell me which library is the best.
In your title you use the word "quickly". Theres no such thing, unless you have a cache implementation. As you pointed out those two libraries help in retrieving images from the web and displaying them into imageView, also support cache features so that images previously displayed can load faster in the near future.
Simple example of Picasso:
Picasso.get().load("http://i.imgur.com/DvpvklR.png").into(imageView);
Want to know more about cache in Picasso? Check out this answer
According to this article here both are really nice to be used , but I would suggest Picasso because it just updated to 3.0 + it is lighter than Glide when it comes to :
library size and method count .

Android I want to stream images from online database

I am new to Android so I want to create a background wallpaper app. I made the offline version already which displays images from an array using ImageAdapter.
But I want make it online so that the images will be downloaded and displayed from an online database. What would be the simple and best way to do it? An example would be preferred.
You can use Picasso library. Image loading using Picasso is very easy, you can do it like this way
Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(imageView);
and in their website you can get every details.
and another Library is Glide. You can use Glide too for loading image..
Just use Picasso, it's pretty simple and lightweight library with good documentation. You also can save images from network with some hacks.

Load multiple images with Glide on Android

I want to make a simple gallery app on Android (like Google Photo or any standard gallery app). I've read that the best way to load images is use Glide library (Google recommends to use it). But how can I load multiple images (from sdcard) using Glide? I can use Glide.with(ctx).load(File file)... for loading single image, but I dont know how to load multiple. And what library does Google Photo uses (it works really great both with local and with cloud images)?
So, the only one way to load images with Glide is to load them one by one using Glide.with(ctx).load(File file)...
But it's not a problem to use it even if we have a lot of images - it works perfectly. And it seems that Google Photo app for Android uses Glide, that's why Google recommend using it.

android slideshow from url

I need to make a horizontal slideshow of images from a URL. I've been searching about and have only found examples with ViewPager showing images from the drawable directory.
There are so many image-load libraries that I don't know what is appropriate for my project, if Picasso or universal image loader or volley...
I tried a universal image loader but seemed very slow actually loading images.
What I need is to get exactly what this application does, which includes a counter images.
Here is the link.
You can try picasso. I used it on this app that I published a couple of days ago.
https://play.google.com/store/apps/details?id=com.jattcode.mikimedia. Is this what you meant. There's an image slider activity if an ad has more than 1 image.

What is the best way to download images using multithreading ?

I'm trying to download image from web. For single image I downloaded successfully. But I want to download more images with multithreading. Any tutorials or leads regarding this will be helpful to me.
As for me, simplest way to do to this - use some third-party library with caching system and post-processing. Most popular is:
1) Picasso from Square team
2) Universal Image Loader
I'm using this library works fine and has a lot of options
